Got to agree, shortly after I first came to Thailand I moved in with a hooker.
She was a real looker but couldn't pay her 10k/month mortgage.
Usually managed 2-3 guys a week in high season, I know 'cos she worked out of my gfs bar.
As for customers being perverts ........
She said 50% of her customers just wanted to cuddle her and cry about their home country wives doing them wrong (no sex), which sounds about right to me.
Did know a go-go girl, she managed 2x a night (+ sponsors).
After a couple of years she had a big car and a nice house all paid for up front.
But she was an unusually hard worker.
